Here's how I found it ( just in case )
<span> x/2 - 3 = 7
Add 3 to both sides
x/2=10
Multiply 2 on both sides

In around 6.35 years, the population will be 1 million.
<h3> how many years will it take for the population to reach one million?</h3>
The population is modeled by the exponential equation:
Then we just need to solve the equation for t:
Let's solve that:
If we apply the natural logarithm to both sides:
So in around 6.35 years, the population will be 1 million.

Answer:
It is the third option: (10C1) (20C1( / 50C2.
Step-by-step explanation:
The number of ways of selecting 2 marbles = the number of combination of any 2 marbles in the 50 marbles in the bag and this is 50C2. It is combinations because the order of drawing the marbles does not matter.
The number of combinations of one being red and the other blue = 10C1 times 20C1.
So the answer is (10C1) (20C1( / 50C2.
